Land Tremor - LVL 6 (This is your second stun, it's also AoE and if you manage to combine it with Charge you make for an deadly opponent.)

Overbearing Clamor - LVL 2 (This skill is excellent for PvP as it decreases the movement speed and removes the magic skills for a certain amount of time, so if you fight several mages at once, this is your weapon of use. AoE.)

DNA:

Potens Dash - LVL 1 (You can use Charge more often, useful if you wish to take down opponents who try to escape.)

Bear-like Stamina Intensification - LVL 10 (As said this is what makes WLs so wanted.)
